    • Since a BeanPostProcessor needs to be instantiated early in order to apply to the initialization of other beans in the context, this early type detection is critical.
    • Because AOP auto-proxying is implemented as a BeanPostProcessor itself, neither BeanPostProcessors nor the beans they reference directly are eligible for auto-proxying, and thus do not have aspects woven into them.

       

      For any such bean, you should see an informational log message: “Bean foo is not eligible for getting processed by all BeanPostProcessor interfaces (for example: not eligible for auto-proxying)“.

    • An ApplicationContext automatically detects any beans that are deployed into it that implement the BeanFactoryPostProcessor interface. It uses these beans as bean factory post-processors, at the appropriate time. You can deploy these post-processor beans as you would any other bean.
    • The PropertyOverrideConfigurer, another bean factory post-processor, resembles the PropertyPlaceholderConfigurer, but unlike the latter, the original definitions can have default values or no values at all for bean properties. If an overriding Properties file does not have an entry for a certain bean property, the default context definition is used.
    • <context:property-override location=“classpath:override.properties"/>
    • You can also use @Autowired for interfaces that are well-known resolvable dependencies: BeanFactory, ApplicationContext, Environment, ResourceLoaderApplicationEventPublisher, and MessageSource.
    • @Bean is a method-level annotation and a direct analog of the XML <bean/> element
